Features. This is a superb
quality zoom lens with a focal length continuously
variable from 70mm to 150mm. Scale markings are
for 80, 90, 105, 120 and 135mm, and intermediate
settings are of course possible. The viewing angle
ranges from 35° to 17, and zoom ratio is 2.
Equipped with a fully automatic diaphragm, this lens has
14 Iens elements mounted in 12 groups which give the
same fine resolving power and sharp focusing
characteristics as individual Takumar lenses.
Turning the zoom ring moves the lens backward or forward
for zoom effect - once the lens has been focused, shots
of moving subjects can be taken in rapid succession at
different focal lengths. Minimum focusing distance is
3.5m, but if the special attachment lens is used, this
can be decreased to 1.9m for close-up shots.
Main
uses. Since this is a zoom lens which combines the
functions of several single lenses with no loss in
quality, its range of uses is practically unlimited.
